ACCURACY
Accuracies apply for 1 year 19°C to 25°C. Temperature coefficient outside these limits is
<0·1 x quoted range accuracy per °C.

Accuracies apply for readings between 400 and 4,000 counts. Additional error at crest
factor = 3 is typically 1%. Input impedance = 10MΩ nominal.
1kΩ unbalanced CMR = >60dB at DC/50Hz/60Hz
